I use the sebastian penetraitt deep strengthening repair masque on clients who have bad split ends and very dry hair. This is a deep conditioning treatment used on people who need extra attention that regular conditioners aren't doing. It smoothed my dry hair and it moisturized my ends leaving it to feel silky and looking very shiny. It works good and I'm always satisfied with it. It smells really good too. It really makes the hair feel and look silky and smooth. It works really good on damaged blonde hair that needs extra attention. You will see a total difference in your hair when you try this. I would recommend this to someone who had breakage, split ends, and damaged unmanageable coarse hair. It is expensive but its worth the money because of the results you get after. I would highly recommend you do this once a week. You'll see results in your hairs structure and texture. It coats each hair strand and seals in the product. You will be amazed with it I gurantee it. Its also color safe which is a good plus to it.
